Morphology

polestar = pole + star (transparent) = pole + star

The components 'pole' + 'star' straightforwardly indicate a star associated with the Earth's pole, so the basic meaning is directly derivable from the bases.

Etymology

Polestar comes from the parts pole and star, meaning a 'star near the pole'. Because this star stays almost still in the sky and points north, sailors used it to find their way, so polestar now means the star that shows north.
